Germany, Berlin—A 96-year-old former Auschwitz administrator will spend the next four years in jail for his role in the mass killings conducted at the concentration camp during WWII.

Oskar Groening, AKA Auschwitz’s bookkeeper, had been responsible for collecting and counting the cash that was stripped from the death-factory’s unfortunate victims.

He had received his sentence in 2015, but his late age and failing health condition had allowed him to remain free; until now, that is.

The Bundesverfassungsgericht, the German Federal Constitutional Court, concluded that Groening’s age and health was irrelevant due to his crimes.
